2021-11-24drm/amd/display: update bios scratch when setting backlightAlex Deucher1-0/+2
Update the bios scratch register when updating the backlight level. Some platforms apparently read this scratch register and do additional operations in their hotkey handlers.

2017-04-04drm/amdgpu: Read vram width from integrated system info tableHarry Wentland1-0/+2
On KB, KV, CZ we should read the vram width from integrated system table, if we can. The NOOFCHAN in MC_SHARED_CHMAP is not accurate. With this change we can enable two 4k displays on CZ again. This use case was broken sometime in January when we started looking at vram_width for bandwidth calculations instead of hardcoding this value. v2: Return 0 if integrated system info table is not available.
